Assessment of repeated relational patterns for individual cases using the SASB-based Intrex questionnaire

Repeated interpersonal patterns are central to case conceptualization and treatment planning in interpersonal and attachment-based approaches to therapy. In this study, raters (133 college students, 165 inpatients) provided data on the Intrex questionnaire (Benjamin, 2000) about self-treatment, relationship with a significant other, and remembered interactions with parents in childhood. Within-subject profiles were inspected for precise behavioral matches conforming to 3 "copy process" (CP) patterns: identification (behaving like an important other), recapitulation (behaving as if the other person is still present and in charge), and introjection (treating the self the way another did). We observed CP evidence in most individual ratings. Consistent with expectation, nonclinical raters tended to copy a securely attached pattern of affiliation, low hostility, and moderate degrees of enmeshment and differentiation. Only patients copied maladaptive behavior at greater than base rate expectation. We discuss implications and provide recommendations for use of Intrex in individual assessment of CP.     

Neither dark age nor renaissance: Research and authorship trends in the experimental analysis of human behavior (1980-1999)

The anniversary of several milestones in the experimental analysis of human behavior (EAHB) provides a prompt for updating previous surveys of EAHB publication trends, which portrayed the field's overall health as good but raised questions about its breadth and trajectory. For the years 1980 through 1999, we examined trends in annual frequency of data-based EAHB articles published in the Journal of the Experimental Analysis of Behavior (JEAB); in the topical emphasis of those EAHB articles; in the geographic region of origin of EAHB articles; and in the relative contributions of new and veteran authors. Our findings show continued productivity in the field, but contradict an earlier report by showing little sustained growth in EAHB over roughly the past 15 years. In terms of authorship, an increasing proportion of EAHB articles are authored by veteran investigators, although the field also benefits from a steady infusion of new authors. International participation in EAHB is limited, with most EAHB research originating in North America. In terms of content, our findings replicate those of previous reports in showing stimulus control and reinforcement and punishment to be the field's most commonly addressed research topics, although content emphases apparently differ across regions of origin. Overall, the data depict EAHB at the close of the 20th century as a multifaceted enterprise, one that is neither bankrupt nor at its full potential for contributing to the overall analysis of behavior. We close with some observations on the value of this type of archival research and some suggestions for improving the archival characterization of the field.     

The relationship between impulsivity, aggression, and impulsive-aggression in borderline personality disorder: an empirical analysis of self-report measures

Impulsivity has been repeatedly identified as a key construct in BPD; however, its precise definition seems to vary especially regarding the overlap with aggression. The term impulsive-aggression , also generally seen as central to an understanding of BPD, seems to address itself to the interface between the two, but has itself been used inconsistently in the literature, sometimes having reference to a unitary phenotypic dimension, and at other times suggesting some combination of distinct traits. This study examined the relationship between multiple measures of impulsivity, aggression, and impulsive-aggression in a BPD sample ( N = 92) in order to clarify the relationship between these measured constructs in this clinical population. Results show little relationship between measures of aggression and impulsivity in BPD, with measures of impulsive-aggression correlating strongly with measures of aggression only. Implications of the present results for future research and clinical work with BPD are discussed.     

Temporal discounting: basic research and the analysis of socially important behavior

Recent basic research on human temporal discounting is reviewed to illustrate procedures, summarize key findings, and draw parallels with both nonhuman animal research and conceptual writings on self-control. Lessons derived from this research are then applied to the challenge of analyzing socially important behaviors such as drug abuse, eating and exercise, and impulsiveness associated with attention deficit hyperactivity disorder. Attending to the broader temporal context in which behavior occurs may aid in the analysis of socially important behavior. Applying this perspective to the study of behavior in natural environments also highlights the importance of combining methodological flexibility with conceptual rigor to promote the extension of applied behavior analysis to a broader array of socially important behaviors.     

Sources cited most frequently in the experimental analysis of human behavior

We conducted an analysis of the sources cited most frequently in primary empirical reports in the experimental analysis of human behavior (EAHB) published in four journals between 1990 and 1999. Citation patterns suggest that modern EAHB is topically focused and relatively independent of both animal operant research and human research conducted outside of behavior analysis.     

Human sensitivity to reinforcement in operant choice: How much do consequences matter?

The results of many human operant conditioning experiments appear to show that humans are less sensitive than nonhumans to operant consequences, suggesting species discontinuities in basic behavioral processes. A reanalysis of 31l data sets from 25 studies employing variable-interval schedules of reinforcement designed to assess sensitivity to reinforcement corroborates the claim that human behavioral allocation among alternatives often deviates from predictions based on rates of experimentally programmed consequences. Close inspection of the studies in question, however, suggests that methodological issues contribute heavily to the differences noted so far between humans and nonhumans and that an explanation based upon species discontinuities is not tenable.     

Bias in self-evaluation: Signal probability effects

Two experiments examined apparent signal probability effects in simple verbal self-reports. After each trial of a delayed matching-to-sample task, young adults pressed either a “yes” or a “no” button to answer a computer-presented query about whether the most recent choice met a point contingency requiring both speed and accuracy. A successful matching-to-sample choice served as the “signal” in a signal-detection analysis of self-reports. Difficulty of matching to sample, and thus signal probability, was manipulated via the number of nonmatching sample and comparison stimuli. In Experiment 1, subjects exhibited a bias (log b) for reporting matching-to-sample success when success was frequent, and no bias or a bias for reporting failure when success was infrequent. Contingencies involving equal conditional probabilities of point consequences for “I succeeded” and “I failed” reports had no systematic effect on this pattern. Experiment 2 found signal probability effects to be evident regardless of whether referent-response difficulty was manipulated in different conditions or within sessions. These findings indicate that apparent signal probability effects in self-report bias that were observed in previous studies probably were not an artifact of contingencies intended to improve self-report accuracy or of the means of manipulating signal probability. The findings support an analogy between simple self-reports and psychophysical judgments and bolster the conclusion of Critchfield (1993) that signal probability effects can influence simple self-reports much as they do reports about external stimuli in psychophysical experiments.     

Efficiently establishing concepts of inferential statistics and hypothesis decision making through contextually controlled equivalence classes

Computerized lessons that reflect stimulus equivalence principles were used to teach college students concepts related to inferential statistics and hypothesis decision making. Lesson 1 taught participants concepts related to inferential statistics, and Lesson 2 taught them to base hypothesis decisions on a scientific hypothesis and the direction of an effect. Lesson 3 taught the conditional influence of inferential statistics over decisions regarding the scientific and null hypotheses. Participants entered the study with low scores on the targeted skills and left the study demonstrating a high level of accuracy on these skills, which involved mastering more relations than were taught formally. This study illustrates the efficiency of equivalence-based instruction in establishing academic skills in sophisticated learners.     

Impact of a Faith-Based Social Justice Course on Pre-Service Teachers

Rapid demographic shifts are occurring around the country. United States’ public schools are more diverse than any time in history. To help prepare pre-service teachers for these shifts, this small-scale qualitative case study explored the impact of a required social justice course for pre-service educators at a large private Christian university in the Southwest United States. Findings suggest that social justice courses for pre-service teachers can have an impact on students’ conceptualizations of social justice and teaching as advocacy, a relationship between students’ Christian perspectives and social justice, and an enhanced role of social justice in students’ personal lives.
